Medias description
Radial spherical plain bearing, requiring maintenance, sliding contact surface: steel/bronze, DIN ISO 12240-1, dimension series K, open design
The GE30-PB INA is a spherical plain bearing. Spherical plain bearings are two-piece plain bearings. They have no rolling elements, but consist of an inner and outer ring. The inner ring has a convex outer surface. The outer ring has a concave inner surface. This construction gives spherical plain bearings their high load carrying capacity and capacity to accommodate misalignment.
The GE30-PB INA has a steel-on-bronze sliding contact. The steel inner ring contacts the bronze surface of the outer ring. The steel-on-bronze sliding contact makes this bearing highly wear-resistant, providing low friction. However, the load capacity is slightly lower compared to spherical plain bearings with steel-on-steel sliding contacts. This bearing needs regular maintenance. Proper lubrication is required to reduce friction and prevent fouling and corrosion.
